Question

As shown in Table, Kp for the equilibrium
N2(g) + 3 H2(g) ⇌ 2 NH3(g)
is 4.51 x10-5 at 450 °C. For each of the mixtures listed
here, indicate whether the mixture is at equilibrium at
450 °C. If it is not at equilibrium, indicate the direction
(toward product or toward reactants) in which the mixture
must shift to achieve equilibrium.
(a) 98 atm NH3, 45 atm N2, 55 atm H2
(b) 57 atm NH3, 143 atm N2, no H2
(c) 13 atm NH3, 27 atm N2, 82 atm H2
